The... majority. of .1 blanks for full-fashioned stockingsaremade .ontwomachines, a legger and. a f6ote'r, "and .large numbers of standard."leggers are 'being'operated in knitting millsin". These standardfull-fashioned this, country. legger machines have threaded spindlescapable of 'imparting,,to'the. stopnuts forthe yarn carrier rodsmovements sufiibientsior single unit.

needs.- However, these machines are not adapted I to makeboth'Lthe leg.and the foot portions of the blank for a stocking, one reason for thisbeing that the means for moving the narrowingcomb's is not designedtopermit said combs to travel a. distance required" to perform all thenarrowing operations necessary to the production-oi a standardfull-Ifashioned stocking. The threaded" portions of the narrowingspindles, if used in the intended manner, are too short when operated toproduceacomplete leg-and-foot blank," and if the nuts for the narrowingcombs are operated in an attempt to produce such a blank theymay' heaccidentally moved beyond the limits to which n these nuts areconfinedin the legger machine,- with the result that the nuts are jammedand their preciseadjustment is disrupted.

Full-fashioned hosiery machines of the single unit type, usually havelonger frames as well as longer spindles for moving the narrowing combs,so that they can not always 'be installedin the space provided forleggers, even if the owners are willing to substitute one for the other,and sacrifice their investment in the leggers.

Further; the formation of a suitable heel pocket requires that the blankfor the "stocking be-widened in the region of the heel. Thishas beendone for single unit stockings in a number i of well known-ways. Heel'pockets produced by widening and narrowing operations of a singleunit'machine have certain recognized-advantages?
